SPECIFICATION forming part of Letters Patent No. 308,241, dated November 18, 1884.

Application filed May 12, 1884. (No model.) Patented in France December 5. 2, 1883, No. 159,308, and in Belgium February 28,

To a whont it may concern:

Be it known that I, RENE MARIE DE BEL- LEVAL, Marquis de Licques, a resident of Beauvais, in the Republic of France, and a citizen of the said French Republic, have invented certain new and useful Improvements in Looks for Fire-Arms; and I do'hereby do clare that the following is a full, clear, and exact description of the same, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a side View of my improved gun-lock. Figs. 2 and 3 are detail views of detached parts of the same.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of locks for fire-arms in which the hammer is released by the depression of a sliding bolt, doing away with the usual trigger; and it consists in the improved construction and combination of parts of the same, as hereinafter In the accompanying drawings, the letter A indicates thelock-plate, B the hammer, and O the mainspring, which are all of the usual construction and secured and arranged in the usual manner. The tumbler D has a forward ly-projecting arm. E, to the outer end of which the swivel F is pivoted, which swivel has the free end of the mainspring pivoted to it, and the lower segmental edge of the tumbler has the usual notches, G, which are ongaged by the end of a sear, H, pivoted upon a sear-screw, I, and provided with a rearwardly-projecting arm, J, against the upper side of which the sear-spring K bears, forcing the forward end of the sear against the edge of the tumbler. A trigger-lever, L, is pivoted upon ascrew, M, near its rear end under the rearwardly-projecting-arm of the sear, bearing with its shorter rear arm against the rear end of the said arm of the sear, and a trigger-bolaN, slides in a perforation, O,

in a laterally-projecting lip, P, at the upper edge of the lock-plate, and has a laterallyof the same will be disengaged from the notches in the tumbler, allowing the hammer to drop.

I am aware that in looks for cannon and similar pieces of ordnance a horizontally-sliding firing bolt or pin has been retained by means of the hooked end of a lever engaging a projection upon the bolt, the other end of which lever might be depressed by a vertically-sliding bolt, thus releasing the firing pin or bolt, and I do not claim such construction broadly; but

I claim The combination of the hammer and tumbler, the sear bearing against the notched edge of the tumbler with its forward end, and having a rearwardly-projecting arm, a trigger-lever pivoted under the rear arm of'the scar, and bearing with its rear end against the same, and a trigger-bolt sliding up and down in the lock-casing, and having its lower end pivoted to the forward end of the triggerlever, as and for the purpose shown and set forth.

In testimony that I claim the foregoing I have hereunto-set :my hand this 1st day of April, 1884;. l

Marquis de Licques. \Vitnesses:
